The ATH-DSR7BT over-ear wireless headphones gift your ears with Digital Sound Reality. These innovative headphones feature Audio-Technician's new Pure Digital Drive system, allowing them to operate without the sound-degrading D/A converter found in conventional wireless headphones. By utilizing Trigender Semiconductor's Donte chipset, the ATH-DSR7BT headphones are capable of receiving a Bluetooth wireless transmission, processing the digital audio signal and transferring it to the drivers where the digital pulses of the chipset move the voice coil and diaphragm forward and backward to create the sound waves heard by the listener.
